FEED-WATER PURIFIEB..

Application filed May 1.8, 1911. v Serial No. 628,016.

To ali whom z' may concern.'

Be it known that I, FRANK E. CKERMAN,

a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Feed-Xliater Puriiers, of which the following is a specification.

This invention relates to water purifying apparatus and has particular application to an apparatusv for purifying the feed water for boilers; Q

In carrying out myinvention, it is my purpose to provide a receptacle through which the water for the boiler is adapted to pass, and in such passage said water is subjected to the action of an electric current passing through a grid formed with va pluwhereby the water is purified "of scale-forming matt-er, and may be conducted directly 'to the boiler.

Still a further object of my invention is to provide a water purifying apparatus, whereby the water in any desired quantity may be rapidly, quickly and economically treated and purified, and it is also my pur pose to produce an apparatus embracing the desired features of simplicity, durability and eiiiciencyl With the above-recited objects and others of a similar nature in view, the invention consists in the construction, combination and arrangement of parts, set forth in and falling within the scope of the appended claims'.

ln the accompanyingfdrawing:eFigure 1 is a vertical longitudinal sectional view, taken through the apparatus embodying my invention'. Fig. 2 is a top plan View, with the cover removed. 3 is a transverse vertical sectional view.

in the present inst-ance, l have shown the preferred Aform of my apparatus wherein employ a-suitable form of receptacle having leading from a suitleading directly tothe boiler, so that. after the water is admitted to the tank or receptacleit is not exposed to the air in its passag-e to the boiler, and thus retains the gases which are liberated by the electrolytic action caused by the passage of an electrical cur. rent through the water within the tank.

Referring nowto the accompanying drawing in detail, the numeral 1 designates a tank iof any suitable size and form and A preferably constructed of metal, said tank Specification of Letters Patent.

Lead-- ing to this tank or receptacle from any suit- 60 able source of supply is an inlet pipe 4, while. an outlet pipe 5l leads from said tank to the boi-ler', (not shown). Within this tank is located my apparatus for setting up electrolytic action, and in the present instance comprises a base vboard 6, and a top board 7, the" two boards being'spacedapart a suitable distance, and .preferably arranged parallel one to the other, the boards being connected at the four corners by vertically arranged U-shaped connecting strips 48 which are -fasv tened by rivets or bolts 9. Resting upon/ the bottom ofthe tank, and between the base board 6 of the frame formed as just described is a board or plate-'10 of wood or'75 other suitable4 material. The base board 6 of the frame'is provided with longitudinally" extending rows of apertures 11, suitably spaced apart, while between 'each row of apertures, rows of apertures and recesses alternate. Similarly, the top board is provided .with longitudinally extending rows of apertures 13, and rows of recesses la arranged between c The numeral 15 designates a metallic con ducting strip, preferably of copper, carryin sockets 16.. At the bottom of the frame`,' employ two of these strips 15, the socket4 thereof projet-ting through the apertures int() the base board, as clearly shown in Figs'. "ll f and 3. At the top of the board ofthe frame, I employ three of these strips 15, thesockets f l'thereof projecting downward throughlthe i apertures 18, and in the the sockets projecting through the board.y Each of the sockets 1G carries a carbon stick.` or electrode extending verticallybetween the f, top and bottom boards of the frame, the carbons carried by the sockets at the top board-11.60 having their lower or free ends itted into the recesses 12 of the base board, while the carbons carried by the sockets 16 at the base4 board extend upwardly and have their upper ends seated 'in the Vrecesses 14 vin the toplq Connectedto the' tank near the top 17- to which is connectedthe cableorwire 18 leading from 'a suitable source of electrical energy while 19 designates aconductor bar or Wire connecting the ends of the top bars 15, said conduc-4 tor 19 being connected to the binding ,post at is a row of recesses 1Q, so that-thefSO I direction reverse to '95 It will thus be lnotedthat .scale-forming solids. 4 y ter pass from the tank to the boiler, it will be in a precipitated state and will not form .20. Similarly the lower conductingstrips 15 are connected by' the lconductor 21 terminat- .ing at the binding post 22, from which leads and destroying or purifying the water of the Should any solid matany incrustation' within the boiler, but may be easily removed from the latter through the blow-olf pipe. If desired, the water as it comesv from thepurifyi'ng tankmay be lum passed through a lsuitable filtering me so as to preventthe percipitated matter from an.' outlet at the opposite ends thereof, a-

entering the boiler with the water.

It will be noted that I have provided an-l exceedingly simple yet ettective means for purifylng water for boiler use, and one which 'requires a comparativelyv small electrode sur-v face for the treatment of a given amount of water, thus necessitating the use of a minimum amoum of electric current so that the cost of maintenance and use of the apparatus is relatively low.

While I have herein shown and described one'particular embodiment of my invention,

Furthermore, it will be seen'v that by arranging all of the carbon electrodes as shown in my preferred form the electric currentvis thoroughly distributed through the water, and when desired t-he ap-V paratus may apart.
